Mysterious UV beads that transform from white to vivid colors with sunlight and blacklight. These are mysterious acrylic beads that are milky white in their normal state, but instantly change color from white to various colors when exposed to ultraviolet rays such as sunlight and blacklight.
They are useful for children's free research, summer vacation science experiments, and as teaching materials for experiencing the amount of UV rays, as you can enjoy the visual gap between white indoors and colorful outdoors.
When the sunlight weakens, they return to milky white, and you can enjoy the color change repeatedly.
By wearing them on your arm as a measure of sunburn prevention, they can also help you gauge the amount of UV rays outdoors.
